Clinical and immunological studies on healthy blood donors hepatitis B antibody carriers.

Ten healthy blood donors persistently seropositive for anti-HBs and without a history of clinically overt viral hepatitis were studied. While physical examination and biochemical liver function tests exhibited normal values in all cases, immunologic studies revealed coexistence of a long-term anti-HBs carrier state with the presence of cell-mediated immunity to HBV antigens and autoantibodies in some. These results suggest a complex immunologic phenomenon underlying the development of the anti-HBs carrier state.

Hepatitis G virus coinfection in chronic hepatitis B and C patients in Poland.

This study evaluated the epidemiology and impact of hepatitis G virus (HGV) infection in patients with chronic hepatitis B and C. Serum samples were obtained from 128 consecutive untreated patients with chronic hepatitis B (72 cases) or C (56 cases). The presence of HGV RNA was determined by PCR amplification of the 5'untranslated region; the sensitivity of the assays was ten template copy equivalents. The prevalence of HGV RNA in hepatitis B and C was found to be 25% and 34%, respectively. HGV-positive and HGV-negative patients did not differ with respect to risk factors for infection, age, sex, or alanine aminotransferase activity. Similarly, there was no difference in the severity of liver disease, as assessed with HAI score. In conclusion, we found a very high prevalence of HGV infection in chronic hepatitis B and C patients in Poland. Nevertheless, no evidence was found that HGV coinfection has any impact on the severity of the underlying disease.

[Evaluation of the treatment of chronic active hepatitis (HBsAg+) with isoprinosine. II. Immunological studies].

A two-month treatment of the chronic active hepatitis (HBsAg+) with isoprinosine produced quantitative and functional T-cells populations in patients with cellular response disorders. Immunological studies have shown that such an effect of isoprinosine lasted for about 4-5 months. Repeated administration of isoprinosine for one month normalized recurrent abnormalities in the monitored immunological parameters.
